SMART STATION

INTRODUCTION Our Smart Station hardware consists of a PIC32MX250 microcontroller with a 3.5mm jack for speakers, a TFT display, keypad, NeoPixel LED ring, microphone, and a host of I2C environmental sensor breakouts: i.e. accelerometer, temperature, humidity, and luminosity sensor breakouts. All of the electronics are neatly contained within a 3D printed casing. Our Smart Station …

Bluetooth Hydration Wearable

Bluetooth Hydration Wearable

Introduction We developed a wearable hydration monitoring system that will track an individual’s hydration levels by measuring the bioimpedance of the skin, that will transmit the data via Bluetooth to his or her cellphone, and that will provide a visual cue corresponding to their hydration. Our completed project! High Level Design Rationale Dehydration is usually …

Final Project Setup

EEG Error Correction Interface

Introduction Our project was an EEG-controlled brain computer interface that allowed a user to correct errors in machine behavior. The project was modeled as a trial-based “game.” In each trial, a solid colored green block or dotted yellow block was placed on a conveyor belt. One end of the conveyor belt had a solid colored …
